MP80 MIDI CONTROLLER OWNERS MANUAL INTRODUCTION Thank you for purchasing the ROLLS MP80 Midi Pedal, it is designed to provide lasting value and usefulness. MIDI provides standardization from which many manufacturers can create products to interface with each other. It has a lot in common with the RS232 for computer data except MIDI is better thought out and is more of a true standard. MIDI is supported for all popular computers, and hardware and software support are increasing daily. Also since it has such wide support, MIDI is now being used for some non musical applications. The ROLLS MP80 is a controller for sending MIDI program change information on any of the 16 MIDI channels. This is done in 10 banks (or groups) of 8 patches (or presets). The 2 digit display shows the bank and patch numbers and does not necessarily equal the MIDI program number being accessed. The left digit is the bank # and the right is the patch # (or preset #). The exact MIDI program # can be found by the formula (bank #+1) X (patch #+1)=MIDI program #. The MIDI channel # is set by dip switches on the front of the unit, switches 1 - 4 off is MIDI channel 1, switches 5 & 6 are not used at this time. The UP and DOWN buttons select the desired bank (0 - 9) but MIDI information is only sent when a patch button (0 through 7) is pressed. INSTALLATION Apply power 7 to 15 volts AC or DC to the power jack on the front of the MP80 or it may be phantom powered through the MIDI jack. While there is no standard for MIDI phantom power there is a convention of pin 1 as ground and pin 3 as hot, the MP80 may be phantom powered by 7 to 25 VDC @ 50 ma.
